Now his marriage appears to be over after his longterm partner Sue Cassidy began divorce proceedings. She filed the paperwork this week, according to TMZ.com.

She tells the website, “This has been looming for some time. I am truly heartbroken that our marriage is ending… I’m glad David is getting the help he needs (in rehab) and I am confident he will come back better and stronger than ever.”

The former couple has reportedly been living apart for around four months.

They married in 1991 and have a son together, 23-year-old Beau Devin Cassidy.
